efficiency

Hi folks! So, my very first diary. After a decade or so...I wanted to share this mess of a grow since the popo came visit me last fall... This strain is fairly common type for my choice, I took some clones from a wonder pie plant that was just popped and it showed great characteristics for...

The question of how much of a certain color is often asked. I'm not professing to know the exact ratios, but attached is a little excel file to help you figure it out. You only need to enter the number of chips, your desired brightness from 0 - 5 and then a custom efficiency if the LEDs are...

Medical card + caretaker home grow planning, looking for criticism/advice about my plan: Looking to run LEDs, I decided on HLG panels without finishing researching other panels, strips, and COBs; picked panels because I need to order parts soon and they seem popular/functional. If you think...

The Brief: They state: 3.03μmol/J This calculates to: 80% efficiency The datasheet calculates: 67.35% efficiency What's the skinny: the difference is from the losses on the phosphor The Claim: LM301H 6500K flux data: LM301H 6500K testing parameters: Digitized LM301H 6500K SPD...

This is hypothetical question of course...But lets say a friend of mine has a decent budget of around 60k to invest in an indoor grow...He lives in an illegal state unfortunately and is looking for ideas on the best methods for staying safe and off the radar while pursuing an op like...

So I ordered the 4x4 kit from Rapid LED that comes with 12 Cree CXB3590 COBs and 3 drivers run at 1400ma (50w). Then they released the 5x5 kit while my order was still processing that runs the Cobs higher at 2100ma (75w). So in my ignorance thinking more watts equals the more bud I will get, I...

Wassup Rollers! I finished up a grow not that long ago. And now my space is sitting vacant. Normally I'd have planted a new bean/s weeks ago. So that the next round can begin asap. However. I've only been using about 2/3 of the floor space I've got. And figured while the box is dormant. I may...

Hello, It's been a while since I checked upon the latest development in growth LEDs, though I noticed that more an more people are experimenting with led Strips. Back in 2015, when I came up with the first citizen COB in this forum, it was all about single, powerful, under-driven chips to...

Hello guys! So I have 10x7 ft room with 6 (hps-600w) lamps and I am thinking to switch myself to LED because of electricity. Whats it the best option for LED? Whats the best option for LED in the terms of efficiency? What is the best substitute for HPS? Whats to you think about Hans Panels...

Hey RIU, I stole Supra's HSUSA table format and made it a bit... sexier. Also, added some functionality to help those of us that use this style of heat sink. This calculator should help you decide what profile to pick if you are considering this route. I'm no expert, and I would love someone...

Hello everyone, I have been waiting patiently for a couple months to see if the COB switch over had any other benefits other than the biggest, frostiest buds I've grown (Check my grow journal, in my sig) or no heat in the grow room and I wanted to contribute by showing an example of the amount...

Hi, sorry for a dumb question but I have read so much and only get more and more cunfused so again I am sorry about it must have to ask myself for direct answer to my question. Found Kingbrite on Alibaba that so many talked about and got these bins for the CXB3070 that I entend to combine with...

Greetings RUI community! Been living on here for a few weeks soaking up all I can from you amazing DIYers. I'm about ready to put together an order for Jerry from Kingbrite, but I am not sure about which drivers I should use with this setup. What I need is a super efficient setup for extreme...

Hello, All. I am presenting a grow using 3 of the California Light Works SolarSystem 550s (400Wx3) and 4 of Timber Grow Lights 200 WATT CREE CXB3590 (4) COB KIT (200Wx4) Currently in week 1 of flower. Total of 24 plants with 3 remaining males to be removed soon. This grow is ran by my friend...

Is having a 1000 Watt HID dimmed to 600 watts the same as having a 600 Watt only HID? does it have the same efficiency?

About 6 clones 10-15 inches high. Different strains, two indica and two sativa. 1000w dual arc (600hps400mh), and lots of room. And don't worry, I understand quick is a relative term. Just looking from the most efficient way to finish my ladies in a timely fashion. Could throw more under but not...

Lets assume over 4sq ft: Setup A: (4) cxb3590 36v 3500k CD on (1) HLG-185h-c1400B dimmed to 50% Setup B: (4) cxb3590 36v 3500k CD on (1) HLG-80h-c700B at 100% power 1. These setups pull approx the same wattage amount from the wall, correct? 2. Is Setup A just as efficient as Setup B...
